WINDOW-SASH.

Specification of Letters Patent No. 8,259, dated July 29, 1851.

things before known, and of the usual man-` ner of making, modifying,and using-the same, reference being had to the accompanying drawingconnected herewith.

My improvement consi-sts in so constructing the bars of the sash as toenable me readily to set a pane or panes of glass without putty, and ina manner perfectly water tight, the process being so simple that anyperson can readily perform it, thus saving all the labor and expense ofglazing in the ordinary way, or removing the sash from its place for thepurpose.

The construction is as follows: The cross bars of the sash are formed oftwo parts, that which is outside of the glass, and which is stationary,and the inner portion that is removable, and serves to hold and bi-ndthe glass in place. The outer part (a), made with any kind of molding,or plain, like the form of the putty employed in glazing, is made on itsinner face perfectly level, and upon it is affixed a strip of indiarubber, upon which the glass is bedded; over this portion of the sash,and in a line with it, there is an inner portion, which consists of abar (o), on which a proper molding is made, which extends from the frameat the side to the center, covering the side of one pane, and at thejunction of four bars at the center, at (c), there is a screw attachedto the stationary part, and extending up beyond a. countersink in theends of the bars, far enough to receive a nut (d) upon it, that coversover the ends of the pieces (b), and binds them into their place. Theinner face of the binding pieces (Z9) has a rib downthrough the center,to separate the glass, or instead thereof there may be a rib on thestationary part (a) the screw at the center may also be reversed,putting a nut into the stationary part, and screwing a broad headedscrew into it; a strip of india rubber may be affixed to the binding bar(b) in addition to the one on the other part; the ends of these bars, itis obvious, lock into the outer frame. I propose not to confine myselfto the use of india rubber for the bed, but to employ any suitableelastic ubstance, such as gutta percha, &c., there- Having thus fullydescribed my improved method of setting glass, what I claim therein asnew, and for which I desire to secure Letters Patent, is

Fastening the bars of two parts, as herein described, by binding themtogether by a screw at the junction of their ends, their opposite endsbeing hooked into the frame of the sash, substantially in the manner andfor the purpose set forth; and in combination with this device, I claimthe elastic bed for the glass to rest against, as above specified.

SEIVALL SHORT.
